Document Summary
Cortical input: brain selects the key areas. Selective attention: a spotlight on important information. Relay nuclei for memory, motor and sensation to the cerebral cortex. Links mammillary (smell and emotion) bodies to cingulate cortex. Determines balance between basal nuclei and cerebellar output to premotor cortex. All of these sensory stop within the thalamus. From the frontal cortex (from memories, thoughts, emotions and ethics), important stuff only get filtered through (called selective attention) Receives blood supply from deep penetrative arteries by posterior and middle cerebral arteries. Everything gets through because there is no filtering. Responsible for regulating the autonomic nervous system. Sends signals to the pineal gland to regulate daily rhythms. Has axons leading to and from the cerebral cortex: cerebral peduncles. The peduncles hold the cerebral cortex like pillars. Are stimulated by eye movements for tracking moving images. Responsible for reflexes that govern the head, eyes, trunk in response to visual stimuli.
